What if I don"t have proof of purchase? Proof of purchase is required on lost or stolen Taco Bell restaurant Gift Card requests for the protection of the cardholder from theft and fraud. Can I get cash back or a refund if I have a balance on my Taco Bell Gift Card? Taco Bell Gift Cards may not be redeemed for cash, except as required by law. Employees at Taco Bell restaurants cannot give you any cash refunds for balances left on cards. In States that require cash refunds on cards, you can print out the Card Service Form and mail it via U.S. Mail with return receipt request with your Taco Bell Gift Card to the address on the Form. Please allow 4-6 weeks processing. Does Taco Bell charge a service fee for unused balances on my Taco Bell Gift Card? No, Taco Bell Gift Cards do not have any fees and the value on the card does not expire.
